The Santa Monica Police Department is asking for the public’s help in locating the driver of a white sedan that struck and injured a pedestrian before fleeing the area on Oct. 31, police said.

The vehicle, believed to be an Infiniti G-series with no front license plate and “major damage to the windshield on the passenger’s side from this collision,” hit a person who was in the crosswalk at Third Street and Wilshire Boulevard at 12:57 a.m., police said.

The pedestrian, identified by her boyfriend as 26-year-old Jordan Moore of Marina del Rey, suffered “serious bodily injury,” but the driver of the vehicle fled the scene, which could result in a felony charge for hit-and-run, police added.

Gregory Dunne, Moore’s boyfriend, said he was holding her hand when she was struck.

“She’s all the sudden ripped from my hands … and she’s 15 or 20 feet down the street,” Dunne said.

Dunne described Moore’s injuries as “just horrible” and “the most tragic thing I’ve ever seen,” but after about a week in the hospital, she’s on the mend.

“She has 10 plates in her skull and face, she’s shattered the humerus bone in her arm, she has a plate and a screw in there, and a major, major concussion,” Dunne said.

Anyone with information is asked to contact Investigator Evan Raleigh at 310-458-8954 or evan.raleigh@santamonica.gov, or call the watch commander at 310-458-8461.
